Minimum Length of Stay (MinLOS)
In hotel revenue management, a minimum length of stay (MinLOS) is a restriction requiring a reservation to cover at least a set number of consecutive nights before it can include a given date.
It is the most used availability control at independent properties, and the one most often left switched on for months after it stopped earning anything.

What is a minimum length of stay?
A floor on stay duration, attached to a date.
A two-night minimum on a Saturday means no reservation may include that Saturday unless it runs at least two nights. A guest arriving Friday for two qualifies. A guest arriving Saturday for two qualifies. A guest wanting Saturday alone does not.
That indifference to which nights is what separates it from closed to arrival, which cares specifically about the first night. A minimum stay shapes duration. Closed to arrival shapes the arrival date. They are frequently used interchangeably and they do different jobs.
Two implementations exist and the difference matters more than it looks. MinLOS by stay date applies the rule to any reservation touching that date. MinLOS by arrival date applies it only to reservations beginning on it. Systems differ in which they default to, and a property that assumes one while its channel manager does the other gets results it did not intend.
The purpose is to stop a high-demand date being consumed by single nights while the nights around it stay empty. On a weekend where everyone wants the Saturday, the restriction is what converts some of that demand into Friday or Sunday occupancy.

How a minimum length of stay works in practice
Applied well it shapes a weekend. Left in place it quietly declines business.
Worked example. A 46-room inn applies a two-night minimum in April to an August Saturday, sensibly, because that weekend sells out most years. Demand runs softer than usual. By 14 days out the Saturday holds 29 of 46 and the restriction is still on, so the remaining 17 rooms can only be sold to guests wanting two nights. At that lead time almost all remaining demand is single nights. The date finishes at 33. Removing the restriction at 14 days out would plausibly have taken it into the low forties. Around ten room nights at $198, or roughly $1,980, was refused by a rule set four months earlier and never revisited.
That is the characteristic failure, and it is far more common than applying the restriction badly in the first place.
The everyday practice is therefore two decisions, not one. Applying it is the easy half and requires only that the date is genuinely strong and the adjacent night genuinely weak. Removing it is the half that needs a system, because nothing will prompt you and the cost is invisible.
The signal to watch is pickup on the restricted date. A date carrying a minimum stay that is still picking up normally is working. A date that has stopped moving while comparable unrestricted dates continue is telling you the restriction has become the constraint.
A softer alternative is worth knowing. Rather than refusing single nights, some properties price them higher, which discourages the pattern without declining it. That is usually the better instrument when demand is uncertain, and it needs no removal discipline at all.

Why a minimum length of stay matters for independent hotels
Because it is the cheapest lever available and the easiest one to misuse.
Applying it costs nothing. There is no discount, no marketing spend and no rate change visible to competitors, yet it can move several room nights onto a Friday that would otherwise have sat empty. On the handful of genuinely strong dates a small property has each year, that is real money for a few minutes of work.
The problem is that independents have no process for taking things off. A chain has a revenue manager whose weekly grid includes restriction review. An owner-operator applies a two-night rule in spring while thinking about the summer, and nothing in the following four months brings it back to their attention.
The other risk is compounding. Multiple weekends carrying old restrictions through a soft season can suppress occupancy in a way that looks like weak demand, which invites exactly the wrong response. A property discounting to fix a problem caused by its own minimum stays is paying twice for one mistake.

How to use a minimum length of stay at your property
- Confirm the adjacent night is genuinely soft. Protecting a Friday that fills anyway costs Saturday rooms for nothing.
- Start at two nights. Three-night minimums suit holiday weekends and very little else at a small property.
- Set a removal date when you set the restriction, and put it somewhere you will actually see it.
- Check whether your system applies it by stay date or arrival date, because the two produce different results.
- Watch pickup on the restricted date weekly. A date that stops moving while comparable dates continue is the signal to remove.
- Consider pricing single nights higher instead when demand is uncertain. It discourages rather than refuses, and needs no removal.
What a minimum length of stay will not do
It does not generate demand for the adjacent night. It redirects demand you already have, and guests who wanted one night will often book a competitor rather than extend.
It cannot tell you what it cost. You see the room nights you gained on the shoulder. You never see the reservations that hit the restriction and went elsewhere, which means the tool systematically looks better than it is.
And it does nothing about rate. A restricted date priced well below what the market would pay is a protected bargain, and the restriction will hold that pattern in place perfectly.
Where restrictions are set and published
A minimum stay is configured in your PMS or your channel manager, and the same rule applies as for rate: keep one system authoritative. A restriction maintained in two places will diverge, and the divergence surfaces as a booking you thought was impossible.
Distribution is where the failures happen. Channels differ in how they support the control, some apply it by arrival date where you meant stay date, and a restriction that did not publish leaves that channel selling the pattern you meant to block. Your own booking engine is often configured separately from the OTA connections and is the one most frequently missed.
There is also a ranking consideration. Heavy or long-running restrictions reduce the number of searches your property can appear in on an OTA, which some platforms treat as a signal. That is a reason to use restrictions precisely rather than broadly, and another reason removal discipline matters.
Verify the same way you verify rates. Once a week, try to book the pattern you meant to refuse, on each channel, and see whether it goes through.
Key takeaways: minimum length of stay
- A rule requiring a reservation to cover a set number of consecutive nights to include a date.
- It shapes duration. Closed to arrival shapes the arrival date. They are not interchangeable.
- Check whether your system applies it by stay date or by arrival date. The results differ.
- The common failure is not applying it badly but leaving it on after demand softened.
- You see the room nights gained and never the bookings refused, so it flatters itself.
- Pricing single nights higher is the softer alternative, and it needs no removal discipline.
Frequently asked questions about minimum length of stay
What is the difference between MinLOS and closed to arrival?
A minimum stay controls how many nights. Closed to arrival controls which night a stay may begin.
A two-night minimum on a Saturday accepts Saturday to Monday just as readily as Friday to Sunday. If the night you actually want to fill is the Friday, that is only half the outcome you were after.
Closed to arrival on the Saturday forces the arrival into the Friday specifically, which is more precise and refuses more business. Use the minimum stay when the number of nights is what matters, and closed to arrival when the particular night is.
When should I apply a minimum stay?
When a date is genuinely strong, the night beside it is genuinely weak, and you have reason to believe multi-night demand exists.
All three conditions matter. A strong date beside another strong date needs no help. A strong date beside a weak one where every guest wants a single night will simply lose you rooms. The restriction assumes a pattern of demand, and when the assumption is wrong it costs you directly.
Holiday weekends, local festivals and event dates are where it earns most, because those genuinely attract travellers willing to stay longer. Ordinary busy Saturdays are a much weaker case.
When should I remove a minimum stay?
The moment it stops being justified, which in practice means you decide the date in advance and then check the evidence weekly.
The evidence is pickup. A restricted date still picking up at a normal rate is fine. A date that has stalled while comparable unrestricted dates keep moving has become constrained by its own rule.
As a default, be sceptical of any minimum stay still in place inside two weeks of arrival. Late demand skews heavily toward single nights, so that is precisely when the restriction does most of its damage and least of its work.
Will a minimum stay hurt my OTA ranking?
It can, because it reduces the number of searches your property is eligible to appear in.
Platforms vary in how they treat this and none of them publish the weighting. The directionally safe assumption is that restrictions which are precise and time-limited cost you little, while blanket minimums running across a season reduce your visibility in a way that outlasts the dates concerned.
That argues for using the tool narrowly. A two-night minimum on six specific dates is a different proposition from a two-night weekend rule applied all summer.
Should a small hotel use minimum stays at all?
Yes, on a small number of dates, with a removal date attached to each.
The tool is genuinely valuable at small properties, because shoulder nights are where the year is decided and a restriction costs nothing to apply. A handful of festival and holiday weekends each year is the natural use.
What small properties should avoid is the standing rule. A permanent two-night weekend minimum is a policy rather than a revenue decision, and it will decline business on every weekend that turns out softer than expected, which is most of them.
